Embodiment Construction
[0017] The working principle and working process of the present invention are as follows: Utilizing the self-adhesiveness of the dispersed straw material or adding a binder, the basic particles of the straw material are bonded and enlarged to form a certain shape and a uniform particle size through forced screw extrusion. block group. And during the forming process, the glass fiber is fed into the glass fiber feeding port, and the glass fiber is laid on it. With the feeding and pushing, the material is fed again at the secondary material feeding port to form the outer structure of the bricklaying.
[0018] Take corn stover, for example.
[0019] Such as Figure 1-3 As shown, in the corn straw brick secondary feeding molding device of the present invention, the rear motor 17 and the large reducer 15 are connected to the large sprocket 19 in the figure to drive the large screw 20 in the primary extrusion barrel 11 to rotate. In order to prevent the shaking and vibration of the...

The invention relates to a straw wall brick-laying forming device, comprising a primary feeding forming device, a secondary feeding forming device and a machine head. The primary feeding molding device includes a primary extrusion barrel, a large screw, and a primary molding cavity, and the secondary molding device includes a secondary extrusion barrel, a small screw, a secondary feeding molding cavity A, and a secondary feeding molding cavity B. The material is added from the feeding port of the primary extrusion cylinder, and after passing through the primary molding cavity, the inner core of the straw brick is preliminarily formed. It is squeezed and pushed by a large screw to the secondary feeding cavity A. The secondary feeding molding cavity A is provided with two glass fiber feeding ports at an angle of 30 degrees from the horizontal. The secondary feeding molding cavity A is connected with the secondary feeding molding cavity B, and the upper, lower, left, and right surfaces of the secondary feeding molding cavity B are respectively provided with four secondary material feeding ports. The secondary extrusion barrel and the small screw are connected left and right in the secondary feeding molding cavity A and the secondary feeding molding cavity B. The invention has a simple structure and improves the strength and compactness of the produced straw bricks.
Description
technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a straw extrusion molding technology. [0002] technical background [0003] my country is a large agricultural country with large output, wide distribution and variety of crop straw, which has been a valuable resource for farmers' life and agricultural development for a long time. However, regarding the utilization of straw, returning the full amount of straw to the field will affect the sowing and growth of crops, and the burning of straw will pollute the atmospheric environment. Therefore, it is necessary to effectively and comprehensively utilize straw and turn waste into treasure. [0004] Existing straw molding mainly has two forms, one is a rolling type, and the other is an extrusion type. The feature of the former is that the fixed plate with the discharge hole is provided with a pressure roller driven by a motor. Due to the contact between the pressure...
